It serves as a direct substitute for OEM reference numbers 05-70-1857 and ESP100-1-8. The sender transmits a signal to the ESP-100 control unit, triggering an alarm or shutdown if pressure drops below a safe threshold.\u003c\/p\u003e\u003ch4\u003eOverview\u003c\/h4\u003e\u003cp\u003eThis pressure sender for Murphy ESP-100 replicates the function of the original 05-70-1857 sender, converting engine oil pressure into an electrical signal for the ESP-100 controller. It is meant for diesel and gas engines equipped with Murphy ESP-100 panels, ensuring accurate monitoring of oil pressure. The unit is built as a service part to replace a worn or failed original sender.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8 NPT thread for direct installation\u003c\/li\u003e\n\u003cli\u003eSingle wire electrical connection compatible with ESP-100 circuits\u003c\/li\u003e\n\u003cli\u003eSealed housing resists oil and vibration\u003c\/li\u003e\n\u003cli\u003eBroad pressure sensing range suited to industrial engines\u003c\/li\u003e\n\u003cli\u003eDirect OEM cross-reference to 05-70-1857 and ESP100-1-8\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Murphy ESP-100 engine protection panels\u003c\/li\u003e\n\u003cli\u003efor Murphy ESP-100 series controllers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMounted on engine block or oil filter housing\u003c\/li\u003e\n\u003cli\u003eWorks with generator sets using ESP-100 shutdown systems\u003c\/li\u003e\n\u003cli\u003eApplied in irrigation pumps and oil field equipment\u003c\/li\u003e\n\u003cli\u003eUsed in marine propulsion engines with ESP-100 monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e05-70-1857, ESP100-1-8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThread Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1\/8 NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnection Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSingle Wire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible System\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMurphy ESP-100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Will this sender work with a Murphy ESP-100 panel that shows a low oil pressure fault?\u003cstrong\u003eA:\u003c\/strong\u003e Yes, a faulty sender can cause false low-pressure readings; replacing it with this unit restores accurate signal output.
